MECHANICAL AIRPLANE TOY.

Application field November This invention relates to improvements inmechanical airplane toys.

The main object of this invention is to provide an inexpensive andeffective toy to simulate an aviator effecting a nose dive.

Another object of this invention is to provide a toy airplane that willdescribe an arc of approximately 180 degrees at each dip or nose dive.

Other objects and novel features of my invention will be apparent as thedescription proceeds.

Referring to the drawings forming part of this specification:

Figure 1 is a side view in elevation showing an embodiment of myinvention. The dot and dash position shown in this figure illustratesthe position of the toy while making the nose dive.

Figure 2 is a botttom plan view of the driving mechanism.

The class of toy here described consists of a body portion 3, made ofsheet metal. A winding key 4 at the forward end of the toy is utilizedto wind up the driving mechanism generally referred to as 5, a spiralpower spring 6, attached to an extension or rod 7 forming a part of thewinding key.

The usual drive gear 8 suitably mounted on the key rod 7, is actuated bythe power spring 6, and in turn drives a pinion 10 fixed to a shaft 11,at the upper end thereof. A mutilated gear 12, is fixed to the lower endof said shaft 11, and meshes alternately with pinions '14, and 15, fixedto an axle 16. A wheel 17 is revolvably mounted at the rear of the toyas at 18, this wheel tends to maintain the toy in normal horizontalrunning position.

When the spring 6 is wound up it will tend to drive the gear 8 in thedirection as, indicated by the arrow and thus impart a movement to themutilated gear 12 in an opposite direction through the medium of thepinion 10, which is secured to the shaft 1.1, that also holds theaforementioned gear 12. F orward motion to the toy is imparted by meansof the pinion 14, fast to shaft 16, said shaft 16, also having securelyfixed thereto a wheel 20, at one end thereof. The shaft 1.6 has at itsother end a loosely mounted wheel 21.

The body and driving mechanism of my toy are so balanced and tending tostop the forward movement of the to will cause the forward end thereofto dip ownwardly and 14, 1825. Serial No; 68,973.

raise the rear or tail end inan upward direction.

It will be understood that the toy will have forward motion only as longas the mutilated gear 12, is in mesh with pinion 1 f, fixedly mounted toshaft 16, said pinion 1.4 imparting rotative movement to the shaft 16and wheel 20 fixed thereto. When the teeth on gear 12 become unmeshedwith the gear 14, they will become engaged or mesh with the teeth onpinion and tend to stop the forward movement of the toy and impart arearward movement thereto. This tendency will cause the forward end ofthe toy to dip down, and owing to the fact that the wheel 21 is looselymounted on the shaft 16, the toy will describe a semicircular are, theloosely mounted wheel 21 acting as a pivot, while the wheel is movingrearwardly. In order that the front end 22, of the toy does not strikethe floor in its dipping position and thus defeat the object of myinvention, I provide a wheel 23 loosely mounted on a pin 24, in a forkedbearing 25, pivotally mounted on a depending rod 26, at the front of thetoy.

When the mutilated gear 12 again comes into mesh with the pinion 14, thetoy will then again be propelled in a forwardly direction. This actionwill be repeated until the power spring 6 needs rewinding.

Having described my invention what 1. claim is:

1. A mechanical toy comprising a body, a motor for propelling said bodyin a forward direction, reversing means in said motor to cause the toyto simulate a nose dive, means for simultaneously describing asemicircular movement with said nose dive simulation, and means forreturning the body to normal position.

2. A mechanical toy comprising a body, an upwardly tilted portion at thefront of the body, a motor mounted in. the tilted front portion, an axleupon which the body is pivoted associated with the motor, groundengaging wheels on the axle and a reversing mechanism in the motor tocause the body to tilt in a downwardly and forwardly direction atpredetermined intervals and then return the body to normal position.

3. A. mechanical toy of the nature described comprising a body, an axleupon which the body is adapted to be pivoted, a pair of ground engagingwheels on the axle, a front portion on said body overhanging beyondtheaxle, a reversing motor mounted in the said front portion adapted toalternately propel the toy in opposite directions and to simultaneouslycause the toy to dip forwardly due to the jar caused by thereversal ofthe motor.

4. A mechanical airplane toy, adapted to periodically simulate a nosedive, comprising a body, an upwardly tilted portion at the front of thebody, a reversing motor mounted in the tilted front portion, an axlejournaledin the body, a mutilated gear on said motor, a plurality ofpfnions fast on the axle alternately in engagement with the mutilatedgear, a ground engaging wheel fast to one end of the axle, a secondground engaging wheel loosely mounted on the opposite end of'theaxle, awheel at the rear of the body normally in engagement with theground, anda pivotally and revolvably mounted wheel at the front of the body toengage the ground when the toy is simulating a nose dive.-

In testimony whereof I hereunto afiix my signature;
